The 'Wlltli' for cooling from tank 46 mm he used over again an it may bereturned from the retort, to the tank by closing valv 93. opening valve91 and admitting compressed air through pipe 16 to force the waterupward into the tank through pipe 52.

It will be seen from the time the processing begins until it iscompleted and the containers are cooled and ready for removal from theretort, that there is a pressure automatically retained within theretort 30 pounds so that at no time. it possible for the internalpressure of the containers to blow off the caps, or the gaskets.

lVhile the apparatus shown is adapted for processing by the directaction oi? steam intermingled with air, it is obvious that the retortmay be heated indirectly by steam confined within suitable coils Withinthe re tort in the well known manner and the invention is not to berestricted to the particular form of apparatus used to illustrate theinvention.

I claim:

'1. An apparatus for studs and the like, including retort, a steamsupply, a coin 'iressed air supply, means for automati ally controllingthe temperati'ire in the retort by steam, and mechanism forautomatically and independently controlling the pressure in the retortby the admission and discharge of com pressed air.
